A remote controlled thymio robot. Base code used in purple mode with some of our own code added.

Step 1: Program the Remote

Materials:
OneForAll Universal Remote integration with Thymio Robot

How to program a remote to a thymio:

1. Set THYMIO to the pre-programmed PURPLE mode
2. Press and hold the SET button.
3. When the LED light flashes twice, press the buttons 1454.

Step 2: How to Use the Remote

Picture of How to Use the Remote

If you can not insert the code or have no use for motion sensors, follow these guidlines. Note: with the code, you can also stop with 5.
4= turn left
6=turn right
2= go forward
8= reverse

When in action, press 8 to cancel actions, but when in reverse, press 2 to cancel actions

When pressing #s twice, action is accelerated.

Can have 2 running at same time (forward, left), or (forward, forward); meaning it just adds to the motor speed (to stop, press opposite of where it is, like (forward, back) or (left, right) or just press center button on robot.

Step 3: Program the Robot

Now connect the Thymio to your computer and insert this code: ( you can use the instructions on the page before or our movie)
